Line 6 Pod Hd500 Drivers Won't Install/download!

Please help! I have downloaded line 6 monkey, POD HD500 edit, and I am still unable to sync my POD with line 6 monkey! For some reason, every single time I launch monkey, it asks for what product I want to configure, and I am constantly having to "download" the HD 500 drivers, but to no avail! my computer says "USB not recognized" or something like that... needless to say. I have had no luck getting my POD to work with monkey... What do I do?
